The user may insert the flexible container420 into the space S1 of the fermentation tank 112, and place themounting part 411 on the seat part 116 as shown in FIG. 14. Thus,beverage ingredient pack 12 can be simply mounted in the fermentationtank 112.

Meanwhile, when the user extracts the beverage ingredient pack 12 fromthe fermentation tank 112, the user may grasp the handle part 441 of themain flow path body 440 with a hand of the user by putting a hand of theuser in the opening of the fermentation tank 112, and upwardly lift thebeverage ingredient pack 12. The beverage ingredient pack 12 may beescaped to the upper side of the opening 111 of the fermentation tank112. Thus, the beverage ingredient pack 12 can be easily extracted fromthe fermentation tank 112.

The flexible tube 460 may guide water or air guided to the pack mainflow path P10 to a deep position in the flexible container 420, andbeverage contained at a lower portion of the flexible container 420 mayeasily flow in the pack main flow path P10 through the flexible tube460.

The flexible tube 460 may be roundly curved or bent at least once in theflexible container 420. The flexible tube 460 may be curved or bentbefore the beverage ingredient pack 12 is inserted into the fermentationtank 112. When air or hot water is supplied to the pack main flow pathP10, the flexible tube 460 may be spread long in the length direction bythe air or hot water.

When the flexible container 420 is maximally expanded, the flexible tube460 may have a length where the bottom end of the flexible tube 460 isspaced apart from the inner bottom end of the flexible container 420.

The bottom end of the flexible tube 460 may be sharply formed, and havea shape of which portion is opened in the circumferential directionthereof.

The flexible tube 460 may have a lower hardness than the main flow pathbody 440. The flexible tube 460 is preferably connected to the tubeconnecting part 432 of the main flow path body 440 after the flexibletube 460 is manufactured separately from the main flow path body 440.

The flexible tube 460 is not connected to the main flow path body 440,but a hollow part through which a fluid can pass may integrally protrudelong at a lower portion of the main flow path body 440. However, in thiscase, the compactness of the beverage ingredient pack 12 may not beeasily performed, or it may be inconvenience for the user to grasp thehandle part 441 with a hand of the user, depending on the hardness ofthe main flow path body 440. More specifically, the hardness of theentire main flow path body 440 may be formed low such that the hollowpart can be curved or bent. In this case, when the user grasps thehandle part 441 of a hand of a user, the handle part 441 may also becurved or bent by the hand of the user. In addition, it may not be easyfor the user to grasp the handle part 441 with the hand of the user.

On the contrary, the hardness of the entire main flow path body 440including the hollow part may be formed high such that the hardness ofthe handle part 441 increases. In this case, the main flow path body 440may have a structure in which the hollow part is not curved or bent, andthe compactness of the beverage ingredient pack 12 may not be easilyperformed.

That is, the flexible tube 460 is preferably connected to the main flowpath body 440 after the main flow path body 440 and the flexible tube460 are manufactured separately from each other.

FIG. 22 is a flowchart illustrating a control sequence of the beveragemaker according to some implementations.

The beverage maker of this implementation includes the controller 109.The user may input an operation command of the beverage maker bymanipulating a wireless communication device such as the rotary knob109A, or a remote controller, or a portable terminal. The controller 109may control the beverage maker using a preset program according to aswitching state of the rotary switch 109B or a signal applied to thewireless communication element. Here, the preset program may control thebeverage maker according to a beverage ingredient process of thebeverage maker.

Hereinafter, an operation of the beverage maker of this implementationwill be described as follows. The following description will provide anexample of a beer maker, although implementations may be used to makeany suitable beverage by fermentation.

The beverage maker of this implementation may include a cleansing andsterilizing course for cleansing and sterilizing flow paths in thebeverage maker. The cleansing and sterilizing course may be performedseparately from a beverage brewing course.

The cleansing and sterilizing course is preferably performed before thebeverage brewing course is performed.

In addition, the cleansing and sterilizing course may be performed by auser input during the beverage brewing course. In this case, thecleansing and sterilizing course may be performed in a step in which themain valve 9 is closed and no additive is contained in the supplier 3,such as a primary fermentation step or secondary fermentation step whichwill be described later.

The cleansing and sterilizing course may be performed in a state inwhich the capsules C1, C2, and C3 are not accommodated in the supplier3, and the beverage brewing course may be performed in a state in whichthe capsules C1, C2, and C3 are accommodated in the supplier 3 and thebeverage brewing pack 12 is accommodated in the fermentation tank 112.

Hereinafter, the cleansing and sterilizing course will be firstdescribed.

The user may input a cleansing and sterilizing command through the inputunit, remote controller, or portable terminal provided in the controller109. The controller 109 may control the beverage maker in the cleansingand sterilizing course as the cleansing and sterilizing command isinput.

The user may manipulate the beverage extraction valve to be opened, andthen input the cleansing and sterilizing command through the input unit,remote controller, or portable terminal.

If the micro switch 630 of the beverage extraction valve 62 is turnedon, the controller 109 may turn on the water supply pump 52 and thewater supply heater 53 so as to cleanse and sterilize the flow paths,and turn on the bypass valve 35 and the first, second, and thirdopening/closing valves 313, 323, and 333. In this case, the controller109 may maintain the main valve 9 to be in a closed state. When thebypass valve 35 and the first, second, and third opening/closing valves313, 323, and 333 are turned on, the bypass valve 35 and the first,second, and third opening/closing valves 313, 323, and 333 may all beopened.

When the water supply pump 52 is turned on, water of the water tank 51may be discharged from the water tank 51 to pass through the watersupply pump 52, and flow in the water supply heater 53 to be heated bythe water supply heater 53. The water (i.e., hot water) heated by thewater supply heater 53 may flow in the bypass flow path 34, the firstcapsule accommodation part 31, the second capsule accommodation part 32,and the third capsule accommodation part 33 through the water supplyflow path 4. The water flowing in the bypass flow path 34, the firstcapsule accommodation part 31, the second capsule accommodation part 32,and the third capsule accommodation part 33 may flow in the main flowpath 2. The water flowing in the main flow path 2 may pass through thebeverage extraction flow path 61 and then be discharged through thebeverage extraction valve 62.

In the above-described control of the beverage maker, the water supplyflow path 4, the bypass flow path 34, the bypass valve 35, the firstcapsule accommodation part 31, the second capsule accommodation part 32,the third capsule accommodation part 33, the main flow path 2, thebeverage extraction flow path 61, and the beverage extraction valve 62may be cleansed and sterilized by the hot water heated by the watersupply heater 53.

In the beverage maker, the above-described cleansing and sterilizationmay be performed for a cleansing setting time, and the cleansing andsterilizing step (S100) may be completed after the cleansing settingtime. After the cleansing setting time elapses, the controller 109 mayturn off the water supply pump 52 and the water supply heater 53, andturn off all of the bypass valve 35 and the first, second, and thirdopening/closing valves 313, 323, and 333. When the bypass valve 35 andthe first, second, and third opening/closing valves 313, 323, and 333are turned off, all of the bypass valve 35 and the first, second, andthird opening/closing valves 313, 323, and 333 may be closed.

The user may manipulate the beverage extraction valve to be closed suchthat contamination through the beverage extraction valve 62 is blockedin the cleansing and sterilizing step (S100).

In addition, the beverage maker of this implementation may include thebeverage brewing course for brewing beverage.

Hereinafter, the beverage brewing course will be described.

In order to perform the beverage brewing course, the user may mount thebeverage brewing pack 12 in the fermentation tank 112 by opening thefermentation tank cover 114 and inserting the beverage brewing pack 12into the fermentation tank 112. After that, the user may shut thefermentation tank cover 114, and the beverage brewing pack 12 may beaccommodated and kept in the fermentation tank 112 and the fermentationtank cover 114. In addition, the user may insert the plurality ofcapsules C1, C2, and C3 into the supplier 3 and then cover the pluralityof capsule accommodation parts 31, 32, and 33 with the lid module 37before/after the beverage brewing pack 12 is mounted in the fermentationtank 112.

The user may input a beverage brewing command through the input unit,remote controller, or portable terminal provided in the controller 109.The controller 109 may control the beverage maker in the beveragebrewing course as the beverage brewing command is input.

The controller 109 may initiate a water supplying step (S200) ofsupplying water to the beverage brewing pack 12 in the beverage brewingcourse. In the example of the beverage-making apparatus being beermaker, the water supplying step S200 may be a liquid malt forming stepof forming liquid malt by uniformly mixing malt with hot water.

The controller 109, in the water supply step (S200), may turn on thewater supply pump 52 and the water supply heater 53, turn on the bypassvalve 35, and turn on the main valve 9. The controller 109 may open themain valve 9 by turning on the main valve 9 that is in a turn-off state.The controller 109, in the water supplying step (S200), may maintain thefirst, second, and third opening/closing valves 313, 323, and 333 to beturned off. Meanwhile, the controller 109 may turn on the gas extractionvalve 73 when water is supplied to the beverage brewing pack 12.

Water of the water tank 51 may be discharged from the water tank 51 topass through the water supply pump 52, and flow in the water supplyheater 53 to be heated by the water supply heater 53. The water heatedby the water supply heater 53 may flow in the main flow path 2 bypassing through the water supply flow path 4, the bypass flow path 34,and the bypass valve 35. The water flowing in the main flow path 2 maybe introduced into the beverage brewing pack 12 by passing through themain valve 9. In the example of the beverage-making apparatus being abeer-maker, the hot water introduced into the beer brewing pack 12 maybe mixed with malt accommodated in the beer brewing pack 12, and themalt in the beer brewing pack 12 may be mixed with water to be graduallydiluted. Further in this example of a beer maker, since the hot water issupplied to the beer brewing pack 12, the malt accommodated in the beerbrewing pack 12 can be rapidly and uniformly mixed with the hot water.

In the above-described water supplying step (S200), the bypass flow path34 and the main flow path 2 may be in a state in which the bypass flowpath 34 and the main flow path 2 have already been cleansed andsterilized by the cleansing and sterilizing step (S100), anduncontaminated clean hot water may be supplied to the beverage brewingpack 12.

Meanwhile, in the above-described water supplying step (S200), the watersupply heater 53 preferably heats water to a temperature of 50° C. to70° C., and the controller 109 may control the water supply heater 53according to a temperature sensed by the thermistor 57.

The beverage maker may perform the above-described water supply step(S200) until an amount of water, sensed by the flow meter 56, reaches aset flow rate. If the amount of water, sensed by the flow meter 56,reaches the set flow rate, the water supplying step (S200) may becompleted. When the water supply step (S200) is completed, thecontroller 109 may turn off the water supply pump 52 and the watersupply heater 53, and turn off the bypass valve 35. In addition, thecontroller 109 may turn off the gas extraction valve 73 when the watersupply step (S200) is completed.

The beverage maker, in the above-described water supplying step (S200),may be controlled such that air is introduced into the beverage brewingpack 12.

In addition, the controller 109 may complete the water supply step(S200) by primarily supplying hot water to the inside of the beveragebrewing pack 12, injecting air into the beverage brewing pack 12, andthen secondarily injecting hot water into the beverage brewing pack 12.

As an example of the water supplying step (S200), only a hot watersupplying process may be performed.

As another example of the water supplying step (S200), a primary hotwater supplying process of primarily supplying hot water, an airinjecting process of injecting air, and a secondary hot water supplyingprocess of secondarily injecting hot water may be sequentiallyperformed.

First, the case where only the hot water supplying process is performedas an example of the water supplying step (S200) will be first describedas follows.

When the hot water supplying process is initiated, the controller 109may turn on the water supply pump 52 and the water supply heater 53,turn on the bypass valve 35, and turn on the main valve 9. Thecontroller 109 may turn on the gas extraction valve 73 when the hotwater supplying process is initiated. In addition, when the hot watersupplying process is completed, the controller 109 may turn off thewater supply pump 52 and the water supply heater 53, and turn off thebypass valve 35. The controller 109 may turn off the gas extractionvalve 73 when the hot water supplying process is completed.

Hereinafter, a case where the primary hot water supplying process, theair injecting process, and the secondary hot water supplying process aresequentially performed as another example of the water supplying step(S200) will be described as follows.

When the primary hot water supplying process is initiated, thecontroller 109 may turn on the water supply pump 52 and the water supplyheater 53, turn on the bypass valve 35, and turn on the main valve 9. Inaddition, the controller 109 may turn off the water supply pump 52 andthe water supply heater 53 when the primary hot water supplying processis completed. The controller 109 may maintain the turn-on state of thebypass valve and the main valve 9 when the primary hot water supplyingprocess is completed. The controller 109 may maintain the turn-on stateof the gas extraction valve 73 when the primary hot water supplyingprocess is completed.

When the air injecting process is initiated, the controller 109 may turnon the air injection pump 82. While the air injection pump 82 is beingturned on, air pumped by the air injection pump 82 may be introducedinto the water supply flow path 4 through the air injection flow path81, and then introduced into the beverage brewing pack 12 through thebypass flow path 34, the main flow path 2, and the main valve 9. The airintroduced into the beverage brewing pack 12 may bump into liquid maltto assist the malt and the hot water to be more uniformly mixedtogether.

If a pressure sensed by the pressure sensor 72 is equal to or greaterthan a set pressure, the controller 109 may complete the air injectingprocess, and turn off the air injection pump 82 so as to complete theair injecting process. When the air injecting process is completed, thecontroller 109 may maintain the main valve 9, the bypass valve 35, andthe gas extraction valve 73 to be turned on.

When the secondary hot water supplying process is initiated, thecontroller 109 may turn on the water supply pump 52 and the water supplyheater 53. Like the primary water supply process, water of the watertank 51 may be supplied to the beverage brewing pack 12, and new hotwater may be additionally supplied to the beverage brewing pack 12. Thecontroller 109 may determine whether the secondary hot water supplyingprocess has been completed according to a flow rate sensed by the flowmeter 56 during the secondary hot water supplying process. If the flowrate sensed by the flow meter 56 during the secondary hot watersupplying process reaches a set flow rate, the controller 109 maydetermine that the secondary hot water supplying process has beencompleted, turn off the water supply pump 52 and the water supply heater53, and turn off the main valve 9, the bypass valve 35, and the gasextraction valve 73.

Meanwhile, if the water supplying step (S200) is completed, the beveragemaker may perform a fermentation tank cooling step (S300) of cooling thefermentation tank 112.

The controller 109 may control the compressor 131 and the expansiondevice 133 of the refrigeration cycle apparatus 13 so as to cool thefermentation tank 112. A refrigerant compressed by the compressor 131may be condensed by the condenser 132 and then expanded by the expansiondevice 133. The refrigerant expanded by the expansion device 133 maytake heat from the fermentation tank 112 while passing through theevaporator 134, and be evaporated. The refrigerant passing through theevaporator 134 may be sucked into the compressor 131. The fermentationtank 112 may be gradually cooled when the compressor 131 is driven, andthe beverage brewing pack 12 accommodated in the fermentation tank 112and the liquidized ingredients accommodated in the beverage brewing pack12 may be cooled.

When the fermentation tank 112 is cooled as described above, thebeverage maker may cool the beverage brewing pack 12 to a mediumtemperature, e.g., a temperature of 23° C. to 27° C., and the controller109 may control the compressor 131 according to a temperature sensed bythe temperature sensor 16 installed in the fermentation tank 112. If thetemperature sensed by the temperature sensor 16 exceeds a compressor-ontemperature, the controller 109 may turn on the compressor 131. If thetemperature sensed by the temperature sensor 16 is equal to or less thana compressor-off temperature, the controller 109 may turn off thecompressor 131.

If the temperature sensed by the temperature sensor 16 is equal to orless than the compressor-off temperature at least once after theabove-described fermentation tank cooling step S300 is initiated, thebeverage maker may perform a mixing step (S400) of mixing the liquidizedingredients by supplying air to the inside of the beverage brewing pack12.

The beverage maker may control the compressor 131 to be turned on/offaccording to the temperature sensed by the temperature sensor 16 evenduring the mixing step (S400), and the on/off control of the compressor131 may be continued until additive injecting steps (S500, S600, andS700) which will be describe later are completed.

The controller 109 may turn on the air injection pump 82, and turn onthe bypass valve 35, the main valve 9, and the gas extraction valve 73.While the air injection pump 82 is being turned on, the air pumped bythe air injection pump 82 may be introduced into the water flow path 4through the air injection flow path 81, and then introduced into thebeverage brewing pack 12 through the bypass flow path 34, the main flowpath 2, and the main valve 9. The air introduced into the beveragebrewing pack 12 may bump into liquidized ingredients (e.g., liquid maltin the case of a beer maker) to assist the ingredients and the hot waterto be more uniformly mixed together.

The controller 109 may turn on the air injection pump 82 and mix theliquid malt with air for a mixing set time. If the air injection pump 82is turned on and the mixing set time elapses, the controller 109 mayturn off the air injection pump 82, and turn off the bypass valve 35 andthe gas extraction valve 73. If the mixing set time elapses, thebeverage maker may complete the mixing step (S400).

The beverage maker may perform the additive injecting steps (S500, S600,and S700) after the mixing step (S400).

In the additive injecting steps (S500, S600, and S700), the beveragemaker may simultaneously or sequentially inject an additive of the firstcapsule C1, an additive of the second capsule C2, and an additive of thethird capsule C3.

The controller 109 may sequentially perform an additive injectingprocess (S500) of the first capsule C1, an additive injecting process(S600) of the second capsule C2, and an additive injecting process(S700) of the third capsule C3.

In the additive injecting process (S500) of the first capsule C1, thecontroller 109 may turn on the water supply pump 52, the main valve 9,the first extraction valve 313, and the gas extraction valve 73 for afirst additive set time. When the water supply pump 52 is turned on,water of the water tank 51 may be introduced into the first capsule C1by passing through the water supply pump 52, passing through the watersupply heater 53, and then passing through the water supply flow path 4.The water introduced into the first capsule C1 may be mixed with theadditive accommodated in the first capsule C1, flow in the main flowpath together with the additive accommodated in the first capsule C1,and be injected into the beverage brewing pack 12 through the main flowpath 2. If the first additive set time elapses, the controller 109 mayturn off the water supply pump 52 and the first opening/closing valve313, and complete the additive injecting process (S500) of the firstcapsule C1.

In the additive injecting process (S600) of the second capsule C2, thecontroller 109 may turn on the water supply pump 52 and the secondopening/closing valve 323 for a second additive set time. When the watersupply pump 52 is turned on, water of the water tank 51 may beintroduced into the second capsule C2 by passing through the watersupply pump 52, passing through the water supply heater 53, and thenpassing through the water supply flow path 4. The water introduced intothe second capsule C2 may be mixed with the additive accommodated in thesecond capsule C2, flow in the main flow path 2 together with theadditive accommodated in the second capsule C2, and be injected into thebeverage brewing pack 12 through the main flow path 2. If the secondadditive set time elapses, the controller 109 may turn off the watersupply pump 52 and the second opening/closing valve 323, and completethe additive injecting process (S600) of the second capsule C2.

In the additive injecting process (S700) of the third capsule C3, thecontroller 109 may turn on the water supply pump 52 and the thirdopening/closing valve 333 for a third additive set time. When the watersupply pump 52 is turned on, water of the water tank 51 may beintroduced into the third capsule C3 by passing through the water supplypump 52, passing through the water supply heater 53, and then passingthrough the water supply flow path 4. The water introduced into thethird capsule C3 may be mixed with the additive accommodated in thethird capsule C3, flow in the main flow path 2 together with theadditive accommodated in the third capsule C3, and be injected into thebeverage brewing pack 12 through the main flow path 2. If the thirdadditive set time elapses, the controller 109 may turn off the watersupply pump 52 and the third opening/closing valve 333, and complete theadditive injecting process (S700) of the third capsule C3.

If all of the additive injecting steps (S500, S600, and S700) arecompleted, the beverage maker may perform a supplier remaining waterremoving step (S800) of removing remaining water in the supplier 3.

In the supplier remaining water removing step (S800), the controller 109may turn on the air injection pump 82, turn on the first opening/closingvalve 313, the second opening/closing valve 323, and the thirdopening/closing valve 333, and turn on the main valve 9 and the gasextraction valve 73.

When the air injection pump is turned on, air may pass through the airinjection flow path 81 and the water supply flow path 4 and then besupplied to the first capsule accommodation part 31, the second capsuleaccommodation part 32, and the third capsule accommodation part 33, toblow water remaining in the first capsule accommodation part 31, thesecond capsule accommodation part 32, and the third capsuleaccommodation part 33. The air may be moved to the beverage brewing pack12 together with the remaining water moved in the first capsuleaccommodation part 31, the second capsule accommodation part 32, and thethird capsule accommodation part 33.

The controller 109 may turn on the air injection pump 82 for a remainingwater removing set time. If the remaining water removing set timeelapses, the controller 109 may turn off the air injection pump 82, andturn off the first opening/closing valve 313, the second opening/closingvalve 323, the third opening/closing valve 333, the main valve 9, andthe gas extraction valve 73.

If the remaining water removing set time elapses, the beverage maker maycomplete the supplier remaining water removing step (S800).

After the supplier remaining water removing step (S800) is completed,the beverage maker may sequentially perform a first fermentation step(S900) and a second fermentation step (S1000).

In the primary fermentation step (S900), the controller 109 may controlthe compressor 131 to a primary fermentation target temperature, andcontrol the compressor 131 such that the temperature sensed by thetemperature sensor 16 maintains a primary fermentation set temperaturerange. After the first fermentation step (S900) is initiated, thecontroller 109 may periodically turn on and then turn off the gasextraction valve 73, and store a pressure sensed by the pressure sensor72 in a storage part (not shown) while the gas extraction valve 73 isbeing turned on. If a change in pressure periodically sensed by thepressure sensor 72 exceeds a primary fermentation set pressure, thecontroller 109 may determine that primary fermentation has beencompleted, and complete the primary fermentation step (S900).

After the primary fermentation step (S900) is completed, the controller109 may initiate the secondary fermentation step (S1000). In thesecondary fermentation step (S1000), the controller 109 may control thecompressor 131 to a secondary fermentation target temperature, andcontrol the compressor 131 such that the temperature sensed by thetemperature sensor 16 maintains a secondary fermentation set temperaturerange. After the second fermentation step (S1000) is initiated, thecontroller 109 may periodically turn on and then turn off the gasextraction valve 73, and store a pressure sensed by the pressure sensor72 in the storage part (not shown) while the gas extraction valve 73 isbeing turned on. If a change in pressure periodically sensed by thepressure sensor 72 exceeds a secondary fermentation set pressure, thecontroller 109 may determine that secondary fermentation has beencompleted, and complete the secondary fermentation step (S1000).

If both of the primary fermentation step (S900) and the secondaryfermentation step (S1000) are completed, the beverage maker may performa ripening step (S1100).

In the ripening step (S1100), the controller 109 may wait during aripening time, and control the compressor 131 such that the temperatureof beverage maintains between an upper limit value of a set ripeningtemperature and a lower limit value of the set ripening temperatureduring the ripening time. If the temperature sensed by the temperaturesensor 16 is equal to or less than the lower limit value of the setripening temperature, the controller 109 may turn off the compressor131. If the temperature sensed by the temperature sensor 16 is equal toor greater than the upper limit value of the set ripening temperature,the controller 109 may turn on the compressor 131.

In the beverage maker, if the ripening time elapses, all of the steps ofbrewing beverage may be completed, and the user may extract the beverageby manipulating the beverage extraction valve 62.

If the user manipulates the beverage extraction valve 62 to be opened,the micro switch 630 may be point-contacted, and the controller 109 mayopen the main valve 9 in the state in which all of the steps of brewingthe beverage are completed. In addition, the controller 109 may turn onthe air pump 152 and the air control valve 156.

When the air pump 152 is turned on, air may be supplied to the inside ofthe fermentation tank assembly 11 through the air supply flow path 154.The air supplied to the inside of the fermentation tank assembly 11 maypressurize the beverage ingredient pack 12. When the beverage ingredientpack 12 is pressurized by the air, beverage of which fermentation andripening have been completed in the beverage ingredient pack 12 may flowin the main flow path 2. The beverage flowing in the main flow path 2may pass through the beverage extraction flow path 61, flow in thebeverage extraction valve 62, and then be extracted to the outsidethrough the beverage extraction valve 62.

FIG. 23 is a block diagram illustrating a control configuration of thebeverage maker according to the implementation.

Again, some of the description below will describe an example in whichthe beverage-making apparatus is a beer maker. However, implementationsare not limited therefore, as the described cleansing and sterilizingmay be implemented in any suitable beverage-making apparatus thatimplements fermentation as described above.

Referring to FIG. 23, the controller 109 may sense on/off of the microswitch 630. Also, the controller 109 may receive measurement values fromthe flow meter 56, the thermistor 57, the pressure sensor 72, and thetemperature sensor 16.

Meanwhile, the controller 109 may control on/off of various types ofvalves included in the beverage maker. Each of the valves may be openedwhen the valve is turned on, and be closed when the valve is turned off.

In more detail, the controller 109 may control on/off of the first,second, and third opening/closing valves 313, 323, and 333, the mainvalve 9, the bypass valve 35, the gas opening/closing valve 73, and theair control valve 156.

The controller 109 may control on/off of the first, second, and thirdopening/closing valves 313, 323, and 333. The first, second, and thirdopening/closing valves 313, 323, and 333 may be installed in the first,second, and third supplier entrance flow paths 311, 321, and 331,respectively. When the first, second, and third supplier entrance flowpaths 311, 321, and 331 are turned on, water or air flowing in the watersupply flow path 4 may be introduced into each of the first, second, andthird capsule accommodation parts 31, 32, and 33 of the supplier 3. Onthe other hand, when the first, second, and third supplier entrance flowpaths 311, 321, and 331 are turned off, the water or air flowing in thewater supply flow path 4 cannot be introduced into each of the first,second, and third capsule accommodation parts 31, 32, and 33 of thesupplier 3.

The mainvalve 9 may be installed in the main flow path 2, and be installedposterior to the connecting part 91 of the main flow path 2 and thebeverage extraction flow path 61 according to the flowing direction ofwater or air. When the main valve 9 is turned on, water or air flowingin the main flow path 2 may be introduced into the beverage brewing pack12, and beverage may be extracted from the beverage brewing pack 12. Onthe other hand, when the main valve 9 is turned off, the water or airflowing in the main flow path 2 cannot be introduced into the beveragebrewing pack 12, and the beverage cannot be extracted from the beveragebrewing pack 12.

The controller 109 may control on/off of the bypass valve 35. The bypassvalve 35 may be installed in the bypass flow path 34. When the bypassvalve 34 is turned on, water or air flowing in the water supply flowpath 4 may flow in the main flow path 2 through the bypass flow path 34.On the other hand, when the bypass valve 34 is turned off, the water orair flowing in the water supply flow path cannot flow in the main flowpath 2 through the bypass flow path 34.

The controller 109 may control on/off of the gas opening/closing valve73. The gas opening/closing valve 73 may be installed in the gasextraction flow path 71. The gas opening/closing valve 73 may beinstalled posterior to the pressure sensor 72 according to the flowingdirection of gas in the gas extraction flow path 71. When the gasopening/closing valve 73 is turned on, air or gas in the beveragebrewing pack 12 may flow to the outside of the beverage brewing pack 12through the gas extraction flow path 71, and a pressure in the beveragebrewing pack 12 may be maintained equal or similar to the externalatmospheric pressure. On the other hand, when the gas opening/closingvalve 73 is turned off, the air or gas in the beverage brewing pack 12cannot flow to the outside of the beverage brewing pack 12 through thegas extraction flow path 71, and the pressure in the beverage brewingpack 12 may become higher than the external atmospheric pressure.

The controller 109 may control on/off of the air control valve 156. Theair control valve 156 may be installed in the air supply flow path 154.When the air control valve 156 is turned on, air may be introduced intoor discharged from the fermentation tank 112 through the air supply flowpath 154 by an operation of the air pump 152. On the other hand, whenthe air control valve 156 is turned off, the air cannot be introducedinto or discharged from the fermentation tank 112 through the air supplyflow path 154.

Meanwhile, the controller 109 may control the water supply pump 52, thewater supply heater 53, the air injection pump 82, the refrigerationcycle apparatus 13, the heater 14, and the air pump 152.

The controller 109 may control the water supply pump 52. The controller109 may control on/off of the water supply pump 52, and control a flowrate of water flowed by the water supply pump 52. When the water supplypump 52 is turned on, water of the water tank 51 may flow in the watersupply flow path 4 by passing through the water supply pump 52.

The controller 109 may control the water supply heater 53. Thecontroller 109 may control on/off of the water supply heater 53, andcontrol a temperature of the water supply heater 53. When the watersupply heater 53 is turned on, water passing through the water supplypump 52 may be heated by the water supply heater 53 to flow in the watersupply flow path 4.

The controller 109 may control the air injection pump 82. The controller109 may control on/off of the air injection pump 82, and control a flowrate of air flowed by the air injection pump 82. When the air injectionpump 82 is turned on, air passing through the air injection pump 82 maybe injected into the air injection flow path 81, and flow in the watersupply flow path 4 through the air injection flow path 81.

The controller 109 may control a temperature controller. In more detail,the controller 109 may control the refrigeration cycle apparatus 13 andthe heater 14. The controller 109 may control on/off of therefrigeration cycle apparatus 13 and the heater 14, and control atemperature of the fermentation tank 112 heated or cooled by therefrigeration cycle apparatus 13 and the heater 14.

A case where the evaporator 134 is installed to be in contact with thefermentation tank 112 will be described as an example. If the compressor131 of the refrigeration cycle apparatus 13 is operated, the temperatureof the fermentation tank 112 may decrease as a heat exchange isperformed between the evaporator 134 and the outer surface of thefermentation tank 112. On the other hand, when the heater 14 is turnedon, the temperature of the fermentation tank 112 may increase as theheater 14 supplies heat to the outer surface of the fermentation tank112.

The controller 109 may control the air pump 152. The controller 109 maycontrol on/off of the air pump 152, and control the flow rate anddirection of air flowing in the air supply flow path 154 by the air pump152. If the air pump 152 is operated to supply air to the fermentationtank 112, the air passing through the air pump 152 may flow in the airsupply flow path 154 to be injected into the fermentation tank 112. Onthe other hand, if the air pump 152 is operated to discharge air of thefermentation tank 112, the air in the fermentation tank 112 may bedischarged through the air supply flow path 154.

Some of the components controllable by the controller 109 may beomitted, changed, or added within a range where those skilled in the artcan invent with ease.

FIG. 24 is a flowchart illustrating a control sequence of a cleansingand sterilizing step of the beverage maker according to someimplementations.

A beverage brewing method of the beverage maker according to someimplementations may include cleansing and sterilizing steps (S100 andS1300) of cleansing and sterilizing the flow paths and the supplier 3 inthe beverage maker.

The cleansing and sterilizing steps (S100 and S1300) may be performedseparately from the beverage brewing course. The cleansing andsterilizing step (S100) may be performed before the beverage brewingcourse is performed, and the cleansing and sterilizing step (S1300) mayalso be performed after the beverage brewing course is performed.Hereinafter, the cleansing and sterilizing step (S100) before thebeverage brewing course will be described, and the cleansing andsterilizing step (S1300) after the beverage brewing course can beidentically understood.

The user may input a cleansing and sterilizing command through the inputunit or rotary knob 109A provided in the controller 100, the remotecontroller, the portable terminal, or the like.

The controller 109 may determine whether the cleansing and sterilizingcommand has been input. If the cleansing and sterilizing command isinput, the cleansing and sterilizing command (S100) may be initiated. Inaddition, the cleansing and sterilizing step (S100) may be automaticallyinitiated before the beverage brewing course.

In the cleansing and sterilizing step (S100), materials may not beaccommodated in the material accommodation part. That is, the first,second, and third capsules C1, C2, and C3 may not be accommodated in thefirst, second, and third capsule accommodation parts 31, 32, and 33,respectively. In addition, the beverage brewing pack 12 is notaccommodated in the fermentation tank 112, but a sterilizing andcleansing pack (not shown) may be accommodated in the fermentation tank112.

In the cleansing and sterilizing step (S100), the sterilizing andcleansing pack may be accommodated in the fermentation tank 112, insteadof the beverage brewing pack 12. Water for performing cleansing andsterilization may be introduced into the sterilizing and cleansing pack.In addition, if the cleansing and sterilizing step (S100) is completed,the sterilizing and cleansing pack may be removed from the fermentationtank 112 by the user.

The controller 109 may control the beverage maker in the cleansing andsterilizing step (S100) using a preset program according to a switchingstate of the rotary switch 109B or a signal applied to the wirelesscommunication element.

If the beverage maker is controlled in the cleansing and sterilizingstep (S100), the controller 109 may display, on the display 109D, astate in which the beverage maker is currently controlled in thecleansing and sterilizing step (S100).

Referring to FIG. 24, the cleansing and sterilizing step (S100) mayinclude a first sterilizing step (S110), a first cleansing step (S130),a second sterilizing step (S150), a second cleansing step (S170), and awater discharging step (S190). The steps may be sequentially performed.

In the cleansing and sterilizing step (S100), the second sterilizingstep (S150), the second cleansing step (S170), the first sterilizingstep (S110), the first cleansing step (S130), and the water dischargingstep (S190) may be sequentially performed. Only some steps among thefirst sterilizing step (S110), the first cleansing step (S130), thesecond sterilizing step (S150), the second cleansing step (S170), andthe water discharging step (S190) may be performed.

In the first sterilizing step (S110), hot water heated by the watersupply heater 53 may perform sterilization by flowing in the supplier 3,the bypass flow path 34, the main flow path 2, and the main flow pathconnecting part 115. Also, the hot water may perform the sterilizationby being introduced into the sterilizing and cleansing pack through themain tube 220 and the main flow path part 230 of the fermentation tankcover 114 and the inner hollow part 430.

In the first cleansing step (S130), water at a normal temperature mayperform cleansing by flowing in the supplier 3, the bypass flow path 34,the main flow path 2, and the main flow path connecting part 115. Also,the water may perform the cleansing by being introduced into thesterilizing and cleansing pack through the main tube 220 and the mainflow path part 230 of the fermentation tank cover 114 and the innerhollow part 430. In addition, the sterilizing and cleansing pack may becompressed by the air pump 152 such that the water in the sterilizingand cleansing pack is discharged to the outside of the beverage makerthrough the gas extraction flow path 71.

In the second sterilizing step (S150), hot water heated by the watersupply heater 53 may perform sterilization by flowing in the supplier 3,the bypass flow path 34, and the main flow path 2. Also, the hot watermay perform the sterilization by being discharged to the beverageextraction valve through the beverage extraction flow path 61.

In the second cleansing step (S170), water at the normal temperature mayperform cleansing by flowing in the supplier 3, the bypass flow path 34,and the main flow path 2. Also, the water may perform the cleansing bybeing discharged to the beverage extraction valve 62 through thebeverage extraction flow path 61.

In the water discharging step (S190), air flowed in the water supplyflow path 4 by the air injection pump 82 may remove water remaining in asterilizing and cleansing process by flowing in the supplier 3, thebypass flow path 34, and the main flow path 2. The air flowing in themain flow path 2 may be discharged together with the remaining water tothe beverage extraction valve 62 through the beverage extraction flowpath 61. Alternatively, the air flowing in the main flow path 2 may beintroduced together with the remaining water into the sterilizing andcleansing pack accommodated in the fermentation tank 112 by passingthrough the fermentation tank cover 114.

FIG. 25 is a flowchart illustrating a detailed control sequence of thefirst sterilizing step shown in FIG. 24.

Referring to FIG. 25, the controller 109 may initiate the firststerilizing step (S110). The first sterilizing step (S110) may includecontrol steps (S111 to S120) which will be described later.

If the first sterilizing step (S110) is initiated, the controller 109may determine whether the micro switch 630 of the beverage extractionvalve 62 is in an off-state (S111).

If the micro switch 630 is turned on, the controller 109 may turn offthe water supply pump 52 and the water supply heater 53. Simultaneously,the controller 109 may display an error signal on the display 109D(S112).

If the water supply pump 52 and the water supply heater 53 had beenpreviously in the off-state, the water supply pump 52 and the watersupply heater 53 may continuously maintain the off-state.

The error signal may include a notification that the beverage extractionvalve 62 is to be closed. Alternatively, the error signal may include anotification that the rotating lever 620 is to be returned to theoriginal position.

If the user returns the rotating lever 620 to the original position byviewing the error signal displayed on the display 109D, the liftingvalve body 610 included in the beverage extraction valve 62 may movedown, and the manipulating projection 614 protruding as the liftingvalve body 610 moves down may be separated from the micro switch 630.

That is, if the user returns the rotating lever 620 to the originalposition, the micro switch 630 may be turned off as the manipulatingprojection 612 being in contact therewith is separated, and thecontroller 109 may detect that the micro switch 630 has been turned off.

In the entire first sterilizing step (S110), if the micro switch 630 isturned on, the controller 109 may turn off the water supply pump 52 andthe water supply heater 53. This is because, if the micro switch 630 isturned on, hot water is discharged to the beverage extractor 6.Simultaneously, the controller 109 may display an error signal on thedisplay 109D.

Meanwhile, the micro switch 630 is turned off, the controller 109 mayturn on the first, second, and third opening/closing valves 313, 323,and 333, the bypass valve 35, the main valve 9, the air control valve156, and the gas opening/closing valve 73 (S113).

If the first, second, and third opening/closing valves 313, 323, and333, the bypass valve 35, the main valve 9, the air control valve 156,and the gas opening/closing valve 73 had been previously in an on-state,the controller 109 may maintain the on-state of the first, second, andthird opening/closing valves 313, 323, and 333, the bypass valve 35, themain valve 9, the air control valve 156, and the gas opening/closingvalve 73.

When the first, second, and third opening/closing valves 313, 323, and333 are turned on, water flowing in the water supply flow path 4 mayflow in the main flow path 2 by passing through the first, second, andthird capsule accommodation parts 31, 32, and 33 as the materialaccommodation parts of the supplier 3.

When the bypass valve 35 is turned on, the water flowing in the watersupply flow path 4 may flow in the main flow path 2 through the bypassflow path 34.

When the main valve 9 is turned on, water flowing in the main flow path2 may be introduced into the fermentation tank 112 through the main flowpath connecting part 115.

When the air control valve 156 is turned on, the pressure in thefermentation tank 112 may be constantly maintained. Therefore, if wateris introduced into the sterilizing and cleansing pack accommodated inthe fermentation tank 112, the sterilizing and cleansing pack may beunfolded or expanded to swell.

When the gas opening/closing valve 73 is turned on, steam caused by hotwater introduced into the sterilizing and cleansing pack may flow in thegas extraction flow path 71, so that the pressure in the sterilizing andcleansing pack can be constantly maintained.

The controller 109 may turn on the water supply pump 52 (S114).

When the water supply pump 52 is turned on, water of the water tank 51may be discharged from the water tank 51 to pass through the watersupply pump 52. The water flowed by the water supply pump 52 may beintroduced into the water supply flow path 4 by passing through thewater supply heater 53.

The controller 109 may determine whether a flow rate measured by theflow meter 56 is within an error range of a first set flow rate M1(S115). In this case, the error range may mean a predetermined numericalvalue range (between M1−a and M1+a) based on the first set flow rate M1.

The first set flow rate M1 is preferably 0.2 LPM.

The flow meter 56 that measures a flow rate of the water supply pumpoutlet flow path 55 may be installed in the water supply pump outletflow path 55. The flow meter 56 may measure a flow rate of waterintroduced into the water supply heater 53.

If the flow rate measured by the flow meter 56 is greater by apredetermined numerical vale “a” or more than the first set flow rateM1, the controller 109 may control a number of revolutions of the watersupply pump 52 to be decreased. If the flow rate measured by the flowmeter 56 is smaller by the predetermined numerical value “a” or morethan the first set flow rate M1, the controller 109 may control thenumber of revolutions of the water supply pump 52 to be increased.

If the flow rate measured by the flow meter 56 is within the error rangeof the first set flow rate M1, the controller 109 may turn on the watersupply heater 53 (S116).

When the water supply heater 53 is turned on, water of the water tank 51may be discharged from the water tank 51 to pass through the watersupply pump 52, and flow in the water supply heater 53 to be heated bythe water supply heater 53. The water (i.e., hot water) heated by thewater supply heater 53 may flow in the bypass flow path 34, the firstcapsule accommodation part 31, the second capsule accommodation part 32,and the third capsule accommodation part 33 through the water supplyflow path 4. The hot water flowing in the bypass flow path 34, the firstcapsule accommodation part 31, the second capsule accommodation part 32,and the third capsule accommodation part 33 may flow in the main flowpath 2, and be introduced into the fermentation tank 112 through themain flow path connecting part 115. In more detail, the hot waterflowing in the main flow path 2 may be introduced into the sterilizingand cleansing pack by passing through the main tube 220 and the mainflow path part 230 of the fermentation tank cover 114 and the innerhollow part 430.

In the above-described control, the water supply flow path 4, the bypassflow path 34, the first capsule accommodation part 31, the secondcapsule accommodation part 32, the third capsule accommodation part 33,the main flow path 2, the main flow path connecting part 115, the maintube 220, the main flow path part 230, and the inner hollow part 430 maybe sterilized by the hot water heated by the water supply heater 53.

The controller 109 may determine whether a temperature measured by thethermistor 57 is within an error range of a first set temperature K1(S117). In this case, the error range may mean a predetermined numericalvalue range (between K1−b and K1+b) based on the first set temperatureK1.

The first set temperature is preferably 70° C.

The thermistor 57 may be installed in at least one of the water supplyheater 53 and the water supply flow path 4, and measure a temperature ofwater passing through the water supply heater 53.

If the temperature measured by the thermistor 57 is higher by apredetermined numerical value “b” or more than the first set temperatureK1, the controller 109 may control a caloric value of the water supplyheater 53 to be decreased. If the temperature measured by the thermistor57 is lower by the predetermined numerical value “b” or more than thefirst set temperature K1, the controller 109 may control the caloricvalue of the water supply heater 53 to be increased.

If the temperature measured by the thermistor 57 is within the errorrange of the first set temperature K1, the controller 109 may start atimer (S118).

The controller 109 may determine whether a time of the timer hasexceeded a first set time t1 (S119).

Until before the time of the timer reaches the first set time t1, thewater supply flow path 4, the bypass flow path 34, the first, second,and third capsule accommodation parts 31, 32, and 33, the main flow path2, the main flow path connecting part 115, the main tube 220, the mainflow path part 230, and the inner hollow part 430 may be continuouslysterilized by the hot water heated by the water supply heater 53.

If the time of the timer exceeds the first set time t1, the controllermay turn off the water supply heater 53 (S120). The timer may be ended.Accordingly, the first sterilizing step (S110) may be completed, and thefirst cleansing step (S130) may be initiated.

FIG. 26 is a flowchart illustrating a detailed control sequence of thefirst cleansing step shown in FIG. 24.

Referring to FIG. 26, the controller 109 may initiate the firstcleansing step (S130). The first cleansing step (S130) may includecontrol steps (S131 to S138) which will be described later.

If the first cleansing step (S130) is initiated, the controller 109 maystart the timer (S131).

Currently, the water supply pump 52 may be turned on, and the watersupply heater 53 may be turned off. Therefore, water of the water tank51 may be discharged from the water tank 51 to pass through the watersupply pump 52, and flow in the water supply flow path 4 by passingthrough the water supply heater 53. In this case, since the water supplyheater 53 is turned off, the water flowing in the water supply flow path4 may be water at the normal temperature, which is not heated.

The water flowing in the water supply flow path 4 may flow in the bypassflow path 34, the first capsule accommodation part 31, the secondcapsule accommodation part 32, and the third capsule accommodation part33. The water flowing in the bypass flow path 34, the first capsuleaccommodation part 31, the second capsule accommodation part 32, and thethird capsule accommodation part 33 may flow in the main flow path 2,and be introduced into the fermentation tank 112 through the main flowpath connecting part 115. In more detail, the water flowing in the mainflow path 2 may be introduced into the sterilizing and cleansing pack bypassing through the main tube 220 and the main flow part 230 of thefermentation tank cover 114 and the inner hollow part 430.

In the above-described control, the water supply path 4, the bypass flowpath 34, the first capsule accommodation part 31, the second capsuleaccommodation part 32, the third capsule accommodation part 33, the mainflow path 2, the main flow path connecting part 115, the main tube 220,the main flow path part 230, and the inner hollow part 430 may becleansed by the water at the normal temperature.

The controller 109 may determine whether a time of the timer hasexceeded a second set time t2 (S132).

Until before the time of the timer reaches the second set time t2, thewater supply path 4, the bypass flow path 34, the first, second, andthird capsule accommodation parts 31, 32, and 33, the main flow path 2,the main flow path connecting part 115, the main tube 220, the main flowpath part 230, and the inner hollow part 430 may be continuouslycleansed.

If the time of the timer exceeds the second set time t2, the controller109 may turn off the water supply pump 52 (S133). The timer may beended.

The controller 109 may turn on the air pump 152 (S134).

Water performing sterilization and cleansing may be in a state in whichthe water is accommodated in the sterilizing and cleansing pack. In thiscase, the air pump 152 may increase the pressure in the fermentationtank 112 by supplying air to the inside of the fermentation tank 112through the air supply flow path 154. Therefore, the sterilizing andcleansing pack may be compressed by a pressure difference. If thesterilizing and cleansing pack is compressed, the water accommodated inthe sterilizing and cleansing pack may be discharged to the outside ofthe beverage maker through the gas extraction flow path 71.

The controller 109 may start the timer (S135).

The controller 109 may determine whether a time of the timer hasexceeded a third set time t3 (S136).

Until before the time of the timer exceeds the third set time t3, thesterilizing and cleansing pack may be continuously compressed as the airpump 152 is operated.

If the time of the timer exceeds the third set time t3, the controller109 may turn off the air pump 152 (S137). The timer may be ended. Afterthat, the user may remove the empty sterilizing and cleansing pack fromthe fermentation tank 112.

The controller 109 may turn off the first, second, and thirdopening/closing valves 313, 323, and 333, the bypass valve 35, the mainvalve 9, the air control valve 156, and the gas opening/closing valve 73(S138).

Accordingly, the first cleansing step (S130) may be completed.

However, the steps (S134 to S137) of removing the water from thesterilizing and cleansing pack may not be included in the firstcleansing step (S130). After that, the user may remove the sterilizingand cleansing pack containing water.

FIG. 27 is a flowchart illustrating a detailed control sequence of thesecond sterilizing step shown in FIG. 24.

Referring to FIG. 27, the controller 109 may initiate the secondsterilizing step (S150). The second sterilizing step (S150) may includecontrol steps (S151 to S160) which will be described later.

Hereinafter, descriptions of contents overlapping with those of theabove-described first sterilizing step (S110) are omitted, anddifferences from the above-described first sterilizing step (S110) willbe mainly described.

If the second sterilizing step (S150) is initiated, the controller 109may determine whether the micro switch 630 of the beverage extractionvalve 62 is in the on-state (S151).

If the micro switch 630 is turned off, the controller 109 may turn offthe water supply pump 52 and the water supply heater 53. Simultaneously,the controller 109 may display an error signal on the display 109D(S152).

The error signal may include a notification that the beverage extractionvalve 62 is to be opened. Alternatively, the error signal may include anotification that the rotating lever 620 is to be pulled.

If the user pulls the rotating lever 620 by viewing the error signaldisplayed on the display 109D, the lifting valve body 610 included inthe beverage extraction valve 62 may move up, and the manipulatingprojection 612 may be in contact with the micro switch 630 as thelifting valve body 610 moves up.

That is, if the user pulls the rotating lever 620, the manipulatingprojection 612 may be in contact with the micro switch 630 to be turnedon, and the controller 109 may detect that the micro switch 630 has beenturned on.

In the entire second sterilizing step (S150), if the micro switch 630 isturned off, the controller 109 may turn off the water supply pump 52 andthe water supply heater 53. This is because, if the micro switch 630 isturned off, hot water cannot be discharged to the beverage extractor 6.Simultaneously, the controller 109 may display an error signal on thedisplay 109D.

Meanwhile, if the micro switch 630 is turned on, the controller 109 mayturn on the first, second, and third opening/closing valves 313, 323,and 333 and the bypass valve 35 (S153). The main valve 9, the aircontrol valve 156, and the gas opening/closing valve 73 may maintain theoff-state.

Since the main valve 9 is in the off-state and the beverage extractionvalve 62 is in the on-state, water flowing in the main flow path 2cannot be introduced into the fermentation tank 112, and may flow in thebeverage extraction flow path 61 to be discharged to the outside of thebeverage maker through the beverage extraction valve 62.

The controller 109 may turn on the water supply pump 52 (S154).

The controller 109 may determine whether a flow rate measured by theflow meter 56 is within an error range of a second set flow rate M2(S155). In this case, the error range may mean a predetermined numericalvalue range (e.g., between a value M2−a and a value M2+a) based on thesecond set flow rate M2.

The second set flow rate is preferably 0.2 LPM.

If the flow rate measured by the flow meter 56 is greater by apredetermined numerical value “a” or more than the second set flow rateM2, the controller 109 may control a number of revolutions of the watersupply pump 52 to be decreased. If the flow rate measured by the flowmeter 56 is smaller by the predetermined numerical value “a” or morethan the second set flow rate M2, the controller 109 may control thenumber of revolutions of the water supply pump 52 to be increased.

If the flow rate measured by the flow meter 56 is within the error rangeof the second set flow rate M2, the controller 109 may turn on the watersupply heater 53 (S156).

When the water supply heater 53 is turned on, water (i.e., hot water)heated by the water supply heater 53 may flow in the bypass flow path34, the first capsule accommodation part 31, the second capsuleaccommodation part 32, and the third capsule accommodation part 33through the water supply flow path 4. The hot water flowing in thebypass flow path 34, the first capsule accommodation part 31, the secondcapsule accommodation part 32, and the third capsule accommodation part33 may flow in the main flow path 2. The hot water flowing in the mainflow path 2 may flow in the beverage extraction flow path 61, and bedischarged to the outside of the beverage maker through the beverageextraction valve 62.

In the above-described control, the water supply flow path 4, the bypassflow path 34, the first capsule accommodation part 31, the secondcapsule accommodation part 32, the third capsule accommodation part 33,the main flow path 2, the beverage extraction flow path 61, and thebeverage extraction valve 62 may be sterilized by the hot water heatedby the water supply heater 53.

The controller 109 may determine whether a temperature measured by thethermistor 57 is within an error range of a second set temperature K2(S157). In this case, the error range may mean a predetermined numericalvalue range (between K2−b and K2+b) based on the second set temperatureK2.

The second set temperature K2 is preferably 70° C.

If the temperature measured by the thermistor 57 is higher by apredetermined numerical value “b” or more than the second settemperature K2, the controller 109 may control a caloric value of thewater supply heater 53 to be decreased. If the temperature measured bythe thermistor 57 is lower by the predetermined numerical value “b” ormore than the second set temperature K2, the controller 109 may controlthe caloric value of the water supply heater 53 to be increased.

If the temperature measured by the thermistor 57 is within the errorrange of the second set temperature K2, the controller 109 may start thetimer (S158).

The controller 109 may determine whether a time of the timer hasexceeded a fourth set time t4 (S159).

Until before the time of the timer reaches the fourth set time t4, thewater supply flow path 4, the bypass flow path 34, the first, second,and third capsule accommodation parts 31, 32, and 33, the main flow path2, the beverage extraction flow path 61, and the beverage extractionvalve 62 may be continuously sterilized by the hot water heated by thewater supply heater 53.

If the time of the timer exceeds the fourth set time t4, the controller109 may turn off the water supply heater 53 (S160). The timer may beended. Accordingly, the second sterilizing step (S150) may be completed,and the second cleansing step (S170) may be initiated.

FIG. 28 is a flowchart illustrating a detailed control sequence of thesecond cleansing step shown in FIG. 24.

Referring to FIG. 28, the controller 109 may initiate the secondcleansing step (S170). The second cleansing step (S170) may includecontrol steps (S171 to S173) which will be described later.

Hereinafter, descriptions of contents overlapping with those of theabove-described first cleansing step (S130) are omitted, and differencesfrom the above-described first cleansing step (S130) will be mainlydescribed.

If the second cleansing step (S170) is initiated, the controller 109 maystart the timer (S171).

Currently, the water supply pump 52 may be in the on-state, and thewater supply heater 53 may be in the off-state. Therefore, water of thewater tank 51 may be discharged from the water tank 51 to pass throughthe water supply pump 52, and flow in the water supply flow path 4 bypassing through the water supply heater 53. In this case, since thewater supply heater 53 is turned off, the water flowing in the watersupply flow path 4 may be water at the normal temperature.

The water flowing in the water supply path 4 may flow in the bypass flowpath 34, the first capsule accommodation part 31, the second capsuleaccommodation part 32, and the third capsule accommodation part 33. Thewater flowing in the bypass flow path 34, the first capsuleaccommodation part 31, the second capsule accommodation part 32, and thethird capsule accommodation part 33 may flow in the main flow path 2.The water flowing in the main flow path 2 may flow in the beverageextraction flow path 61, and be discharged to the outside of thebeverage maker through the beverage extraction valve 62.

In the above-described control, the water supply flow path 4, the bypassflow path 34, the first capsule accommodation part 31, the secondcapsule accommodation part 32, the third capsule accommodation part 33,the main flow path 2, the beverage extraction flow path 61, and thebeverage extraction valve 62 may be cleansed by the water at the normaltemperature.

The controller 109 may determine whether a time of the timer hasexceeded a fifth set time t5 (S172).

Until before the time of the timer reaches the fifth set time t5, thewater supply flow path 4, the bypass flow path 34, the first capsuleaccommodation part 31, the second capsule accommodation part 32, thethird capsule accommodation part 33, the main flow path 2, the beverageextraction flow path 61, and the beverage extraction valve 62 may becontinuously cleansed.

If the time of the time exceeds the fifth set time t5, the controller109 may turn off the water supply pump 52 (S173). The timer may beended.

Accordingly, the second cleansing step (S170) may be completed, and thewater discharging step (S190) may be initiated.

FIG. 29 is a flowchart illustrating a control sequence according to afirst implementation of the water discharging step shown in FIG. 24.

Referring to FIG. 29, the controller 109 may initiate the waterdischarging step (S190).

If the water discharging step (S190) according to this implementation isinitiated, the controller 109 may turn on the air injection pump 82(S191).

Currently, the beverage extraction valve 62 may be in the on-state, andthe first, second, and third opening/closing valves 313, 323, and 333and the bypass valve 35 may be in the on-state. In addition, the mainvalve 9 may be in the off-state.

Therefore, air injected by the air injection pump 82 to be introducedinto the water supply flow path 4 may flow in the bypass flow path 34,the first capsule accommodation part 31, the second capsuleaccommodation part 32, and the third capsule accommodation part 33. Theair flowing in the bypass flow path 34, the first capsule accommodationpart 31, the second capsule accommodation part 32, and the third capsuleaccommodation part 33 may flow in the main flow path 2. The air flowingin the main flow path 2 may flow in the beverage extraction flow path61, and be discharged to the outside of the beverage maker through thebeverage extraction valve 62.

In the above-described control, water remaining in the water supply flowpath 4, the bypass flow path 34, the first capsule accommodation part31, the second capsule accommodation part 32, the third capsuleaccommodation part 33, the main flow path 2, the beverage extractionflow path 61, and the beverage extraction valve 62 may be dischargedtogether with the air to the outside of the beverage maker. That is, theremaining water in the beverage maker may be removed.

The controller 109 may start the timer (S192).

The controller 109 may determine whether a time of the timer hasexceeded a sixth set time t6 (S193).

Until before the time of the timer reaches the sixth set time t6, theair injected by the air injection pump 82 may remove remaining waterwhile flowing along the water supply flow path 4, the bypass flow path34, the first, second, and third capsule accommodation parts 31, 32, and33, the main flow path 2, the beverage extraction flow path 61, and thebeverage extraction valve 62.

If the time of the time exceeds the sixth set time t6, the controller109 may turn off the air injection pump 82 (S194).

The timer may be ended.

The controller 109 may turn off the first, second, and thirdopening/closing valves 313, 323, and 333 and the bypass valve 35 (S195).Accordingly, the water discharging step (S190) may be completed, andsimultaneously, the cleansing and sterilizing step (S100) may becompleted.

The controller 109 may display, on the display 109D, that the cleansingand sterilizing step (S100) has been completed.

FIG. 30 is a flowchart illustrating a control sequence according to asecond implementation of the water discharging step shown in FIG. 24.

Hereinafter, descriptions of contents overlapping with those of thefirst implementation (S190) of the water discharging step are omitted,and differences from the first implementation (S190) of the waterdischarging step will be mainly described.

Referring to FIG. 30, the controller 109 may initiate the waterdischarging step (S190′).

If the water discharging step (S190′) according to this implementationis initiated, the controller 109 may determine whether the micro switch630 of the beverage extraction valve 62 is in the off-state (S191′).

If the micro switch 630 is turned on, the controller 109 may display anerror signal on the display 109D (S192′).

The error signal may include a notification that the beverage extractionvalve 62 is to be closed. Alternatively, the error signal may include anotification that the rotating lever 620 is to be returned to theoriginal position.

If the user returns the rotating lever 620 to the original position byviewing the error signal displayed on the display 109D, the liftingvalve body 610 included in the beverage extraction valve 62 may movedown, and the manipulating projection 612 may be separated from themicro switch 630 as the lifting valve body 610 moves down.

That is, if the user returns the rotating lever 620 to the originalposition, the micro switch 630 may be separated from the manipulatingprojection in contact therewith to be turned off, and the controller 109may detect that the micro switch 630 has been turned off.

If the micro switch 630 is turned off, the controller 109 may turn onthe main valve 9, the air control valve 156, and the gas opening/closingvalve 73 (S193′). In addition, the first, second, and thirdopening/closing valves 313, 323, and 333 and the bypass valve 35 maymaintain the on-state.

The controller 109 may turn on the air injection pump 82 (S194′).

Air flowing in the water supply flow path 4 may flow in the bypass flowpath 34, the first capsule accommodation part 31, the second capsuleaccommodation part 32, and the third capsule accommodation part 33. Theair flowing in the bypass flow path 34, the first capsule accommodationpart 31, the second capsule accommodation part 32, and the third capsuleaccommodation part 33 may flow in the main flow path 2, and beintroduced into the fermentation tank 112 through the main flow pathconnecting part 115. In more detail, the air flowing in the main flowpath 2 may be introduced into the sterilizing and cleansing pack bypassing through the main tube 220 and the main flow path part 230 of thefermentation tank cover 114 and the inner hollow part 430.

In the above-described control, water remaining in the water supply path4, the bypass flow path 34, the first capsule accommodation part 31, thesecond capsule accommodation part 32, the third capsule accommodationpart 33, the main flow path 2, the main flow path connecting part 115,the main tube 220, the main flow path part 230, and the inner hollowpart 430 may be introduced together with the air to the sterilizing andcleansing pack. That is, the remaining water in the beverage maker maybe removed.

The controller 109 may start the timer (S195′).

The controller 109 may determine whether a time of the timer hasexceeded the sixth set time t6 (S196′).

Until before the time of the timer reaches the sixth set time t6, theair injected by the air injection pump 82 may remove the remaining waterwhile flowing along the water supply path 4, the bypass flow path 34,the first, second, and third capsule accommodation parts 31, 32, and 33,the main flow path 2, the main flow path connecting part 115, the maintube 220, the main flow path part 230, and the inner hollow part 430.

If the time of the timer exceeds the sixth set time t6, the controller109 may turn off the air injection pump 82 (S197′). The timer may beended.

The controller 109 may turn off the first, second, and thirdopening/closing valves 313, 323, and 333, the bypass valve 35, the mainvalve 9, the air control valve 156, and the gas opening/closing valve 73(S198′).

FIG. 31 is a graph illustrating changes in temperature measured by thethermistor as a flow rate of the water supply pump is controlled.

Referring to FIG. 31, the controller 109 may control the temperature ofhot water heated by the water supply heater 53 by controlling the numberof revolutions of the water supply pump 52 in the sterilizing andcleansing step (S100).

Graph 1 shown in FIG. 31 is a graph illustrating changes in temperatureof hot water with respect to time when the water supply pump 52 and thewater supply heater 53 are simultaneously turned on. Graph 2 shown inFIG. 31 is a graph illustrating changes in temperature of hot water withrespect to time when the water supply pump 52 and the water supplyheater 53 are sequentially turned on. Hereinafter, this will bedescribed in detail.

In the first sterilizing step (S110) and the second sterilizing step(S150), as described above, the flow paths and the components in thebeverage maker may be sterilized by hot water heated by the water supplyheater 53. In this case, a desired sterilization effect may be generatedonly when the hot water is to have a sufficiently high temperature, andthe sterilization is to be performed for a sufficiently long time.

The water flowed by the water supply pump 52 may be heated by passingthrough the water supply heater 53. In this case, if a flow speed of thewater passing through the water supply heater 53 is excessively fast, aheating time is decreased, and hence, an increase in temperature of thewater may be slowly performed.

Therefore, in order to decrease the time required to reach a desiredtemperature of hot water, preheating of the water supply heater 53 andthe flow speed of water, caused by the number of revolutions of thewater supply pump 52 may be gradually increased at an early stage inwhich heating is started.

To this end, the controller 109 may control the flow rate of waterpassing through the water supply heater 53 by turning on the watersupply pump 52 and then controlling the number of revolutions of thewater supply pump 52 (S115 and S155). After that, the water supplyheater 53 may be turned on, thereby early reaching a desired settemperature (S117 and S157).

Accordingly, the amount of water used in the cleansing and sterilizingstep (S100) can be minimized.

Some of the control steps of the cleansing and sterilizing step (S100and S1300) may be replaced, changed, excluded, or added within a rangein which those skilled in the art may easily modify the control steps.

Through the cleansing and sterilizing step (S100), the beverage makeraccording to the implementation can cleanse and sterilize the inside ofthe supplier and the flow paths. Further, as the cleansing andsterilizing step (S100) is performed before the beverage brewing course,beverage can be sanitarily brewed. Furthermore, as the cleansing andsterilizing step (S100) is performed even after the beverage brewingcourse, a clean state can be maintained even when the beverage maker isnot used.

According to the present disclosure, water introduced into the watersupply flow path flows in the supplier and the main flow path, so thatthe inside of the supplier and the flow paths can be cleansed andsterilized.

Further, cleansing and sterilization can be performed using onlycomponents required to brew beverage.

Further, the water flowing in the main flow path is introduced into thefermentation tank assembly, so that flow paths used when beverage isbrewed can be cleansed and sterilized.

Further, the water flowing in the main flow path is discharged to theoutside through the beverage extraction flow path, so that flow pathsused when beverage is extracted can be sterilized and cleansed.

Meanwhile, the flow path including the main flow path 2, the watersupply flow path 4, the beer extraction flow path 61, the gas extractionflow path 71, the air injection flow path 81, the air supply flow path154, and the like, which are described in the present disclosure, may beformed a hose or tube through which a fluid can pass. The flow path maybe configured with a plurality of hoses or tubes continued in the lengthdirection thereof. The flow path may include two hoses or tubes disposedwith another component such as a control valve, interposed therebetween.

The foregoing implementations are merely exemplary and are not to beconsidered as limiting the present disclosure. This description isintended to be illustrative, and not to limit the scope of the claims.Many alternatives, modifications, and variations will be apparent tothose skilled in the art. The features, structures, methods, and othercharacteristics of the exemplary implementations described herein may becombined in various ways to obtain additional and/or alternativeexemplary implementations.
